1. INSPECT SPARK TEST
Check that the spark occurs.
(1) Disconnect the high±tension cord from the spark plug.
(2) Remove the spark plug.
(3) Install the spark plug to the high±tension cord.
(4) Ground the spark plug.
(5) See if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors during this test, crank the engine for no more
than 5 ± 10 seconds at time.
If the spark does not occur, do the test as follows:
